WEFT BINDING AND SEVEBXNG DEVICE FOR LOOMS.

Specification of Letters Patent. Patented July 18, 1916.

Application filed July 5, 191 Serial No. 849,648.-

To all 'wlumt itmaj con ern Be it known that I, Emsim 1. Beaver:-

' srocK, a citizen of the United States of America, and'resident of l 'lolyokc, in the county of Hampden and State of Massachusetts, have invented certain new and useful 7 Improvementsj'in \Veft Bindin and Severing Devices for Looms. of whic the following is a full, clear; and exact description.

This invention relates to devices or appliances included in'automatic looms of a well known type, in which bobbins, from supplying means therefor, are periodically delivcred into the shuttle, causing the expulsion of the shuttle bobbin from which the weft thread is exhausted", and in the above mentioned type of loomthere is employed a. so called feeler, which cooperates with the more or less filled bob-bin so that when the thread on the bobbin is substantially exhausted, or so that there is but very little thread remaining on the bobbin, the feelcr will cause the rocking of a shaft which actuates the forcing of a fresh filled bobbin from the magazine or bobbin supply into the shuttle simultaneously securing the I expulsion from the shuttle of the exhausted bobbin.

The improvements of the general charac-" ter towhich the present invention relates are set forth in an application for Letters Patent of the United States filed by me -A.pril 3, 1913, Serial No. 758,598, the same including a devieeopposite the location of the mouth or inner end of the shuttle box which is operable to both temporarily bind the weft, and also to sever it near where it is bound at the time when the shuttle is to be replenished \vitha fresh bobbin; holding the end portion of theweft which extends in an outward direction from the selvage; and a second device opposite the location of an intermediate part of the shuttle box which is operable to temporarily bind the. portion of the-weft between the first bind; ing and cutting device and the point where the weft emerges from the shuttle, the said second device beingalso operable to cut. the weft near the point where it is bound by the second device. These devices are provided for the purpose of preventing the remnants of the weftfrom an exhausted bobbin becoming entangled with the weft of the fresh b0 bin to thereby improperly become woven into the cloth. v

. fllhogo ipanion binding and cutting de were.

thc first binder and cutter, is'a thin plate named application, include as to each a single pair of relatively movable binder jaws or members in conjunction with an adjacently. located cutter. Experience-in the employment of these devices shows that the binding of the weft by each of the devices at a single point is not reliable, especially with yarns or thread of certain quality and' degree of fineness; and the object of the present invention is to so construct the companion binding and cutting devices that each will have means for the acquirement'of a plurality of bindings of the weft thread.

at (points comparatively close to each other an all adjacent the point of cutting.

A furtherobject of the invention is .to

provide meansiorsli'ght transverse or lateral adjustments. of theseveraljaws coinprised in the binding-and fiitting devices so that each, thercofnia'y' he set up with a nicety for its best coactigi}. with the part or. member with which it "works-to bind or cut Wit these and other objects in viewltthe invention is described in conjunction with the accompanying drawings and issct forth the we t as the cas e may in the claimsz Imthe drawings :'-Figure 1' is a side elevation of the combined binding and cutting device, the parts thereof being in open position, and as when the device as a whole withdrawn or retired from proximity to the path of the shuttle and tothe lay. Fig. 2 is a view similar toFig. 1,but showing the parts as in their closed relations as assumed when the device as a whole is swung toward the path of the shuttle and to a position to be actuated b the lay. Fig. 3 is a plan view of ig. 1. Fig. 4 is a side elevation of arts of he deviceas seen with some'of t 9 conunctive parts removed. Fig. 5,is, a substan,

tially horizontal longitudinal sectional as taken on line 55, Fig. 1. '6, 7 and 8 are cross sectional views as taken about on the lines 66, Fig. 1, and showing the relations of the parts comprised in the first binding and cutting device at dilfercut times or stages in the operation. Fig. 9

is a side view of the shoe or bufl'erprovide'd on the face of the extremity of the arm which carries the first binder and cutter.

Lying against the face of -the. arm G, which arm forms the oscillatory. support for having-a sharp or shear cutting edge. 0

n and described in my aforeset ands-spaced from this shear y" is a body G formedlwith goose necked extremity G and held immovable in'its position of sep- -.aration from'lihe side of the arm and the shear, in piirt by the transverse stud G and in hart by being held on the pivot stud 'g is formed "of three flat plates facewise ar-' 9. mngcd and united, the intermediate plate thereof and, serving as a spacing memor the outer plates and for the creation i the aforementioned bifurcation G, the iosite boundaries of which are invertical tched with the body G in the' inanner e i. shears, and at opposite sides thereof are the binder plates 7' and j- -united at their heel so portion j by a spacing block and rivets, as

indicated in Fig. 4, these paired binder jaws rocking on the pivot g as likewise does the cutter jaw j w ich lies .facewise relatively to the inner-binder jaw J 2 and'between such jsiw and the fixedcutter or shear jaw jh 'The movable cutter jaw jat the heelportion j of the combined parts is united to the binder jaws by "the transverse rivets, but

from its pivot toward its free or working In the space in the bifurcated extremity of the aforementioned fixed'body Gr also lpivotally hung on the pivot stud g is an angular element 'jZ-the shape of which is best. seen in Fig. 4, and which comprises the tinger or jaw j at its lower portion, a clearer finger i above thecrotch between such fingersand an actuation finger j".

on the carrying arm G is swung-from its retired position rearwardly of-the loom and, toward. or to' the path of the shuttle,

with the j aw devices in their open positions as indicated in Figs; 1 and 6, the'lay in heating up will lining the spring pressed stud e on the top of: the shuttle box against the actuation finger to cause, as shown in Fig.

2 the'part j to be swung so as to carry its binder finger 7" between the jaws G, G", of the fixed body G above the crotch at the extremities of such jaws toqbtain a double :binding of the weft thread two. laces, as shown in Fig. 7. This action is a most instantly followed by a part or abutment on the lay striking the heel portion i of the between the binder jaws j and j. T is body,

us less long than the plateat oppositeend, it is unattached to the adjacent binderi combined, movable binder ja ws and shear aw Zirhereby the latter are swung to their close relationsindicated in Figs. '2 and 8 securing two additional bindingsoi the weft thread below the crotch-in the jaws, and then 0 thereafter the cutting of the thread near where'lt has the plurality of bindings.

The awe are thrown into their open positi0n la tel; the arm has retired forwardly or outwardly following the bobbin replenishinent,.carrying the thread held thereby outwardly away from the path of the shuttle and only to release the thread after it shall have been carried to such out of the way position, by having the stud 2' carried bythe uniting heel i of the binder jaws engage a trip member i represented in dotted lines in Fig. 1 and which is mounted on any suitable support and in any suitable po sition relative to the path of movement of the stud i and incapable of yielding in an r upward direction but capable of yielding. downwardly -so that upon the backward swing of the arm G the stud may ride over the. trip member a? to occupy its position slightly beyond, it and for coaction therewith on the nextinward swing of the arm, a to cause the movable combined jaws to open The mode of and means'for the causing of the combined movable jaws to seasonably have their opening and closing movements are the same as heretofore usually practised and utilized in respect of the cutter jaw and single binder jaw in automatic looms.

As the angular device 7' is swung downwardly to its normal or non-binding position, represented in Fig. 4, the clearer finger j receding in the downward direction to occupy a position about where the binder finger j? had previously been, positively. ejects the looped portion of the thread from between tlui jaws G G7, abacus the crotch in the ciitrcmifty'thereof. The bolt 9 is screw threaded and adjust abletransversely relatively to the arm G and it has a pair 0 shoulders gf and'g closely together on the intermediate pert thereof in engagementat either side of the normally 'fixedicutter jaw ji'the' shank portion of which by the screw 9 is secured on the side 1 of the arm at quite a distance'fr'om the pivot.

These shoulders may be made as collars sore-w threaded or otherwise engaged in their adjace'nt positionsorr the pivot stud, g.

Byloosening the nut g and turning the 2; pivqt stud, such stud may be axially adjusted to carry the extremity of the cutter jaw which extremity is unattached rclatively t0 the arm slightly away from such arm 'to bring it to position for its best shear- 125. ing coaction with the movable cutter j u w j.

In order to impart to the movablezuvs a slight degree oi obliqueness,' they severally havelperforations through an iipper pc ion thereof through which a bolt c traver ws, the 13;

' By loosenihg the nuts;theupper pprtions of the jaws \\'ill, by the spring a, be subject to-a separating force so-that they are slightlytilt-ed on the pivot stud y. so'es to be obhque to the true vertical planes; thereby insuring that the movable binderjiuvswill have their best binding 'coaction with the fixed jaws of the normally stationary body member G. Extending outwardly beyond'theface of the outer binder jaw 7' is the threaded extrenu'ty' of the pivot stud 1 which has thereon a spring, or resilient washer g and a single, or duplicated binding nuts 9, which pro-- vision is eliicient for holding the binder jaws in the adjustmentswhich may be imparted thereto independently of the adjustment whichis impartedjtfi the cutter jaws.

Inasmuch-as transverse adjustments of the cutter jaw j by theaxial movement of the pivot g tend to cause corresponding trans-' \:e rse* displacement and possible distortion of .the aforementioned body G3, provision is made. for asecond adjustment of such body atthe goose neck portion "or shank Gr thereof-,'-the'-same being seen'to consist in the transversegboltor.studGK, the headed end of which'is in =engagement with the parts G while it receives locking'nuts G? andG" on thy-"portion thereof which .-is" threaded When the threaded stud Gf-is turnedto permit the body G to move away from the side'of the arnr G, thespring d betweern the part G and arm; operates to positively efi'cct'such movement, thereby "facilitating in'the 'operation'of adjustment and prevent ingan undue tilting to an oblique position of 'the'shank or goose neck portion of the body G a Th body member in which the fixed binderf jaws G are comprised, has to the rear at the pivot g a longitudinal slot '0 theretiirough .and the opposite movable jaws have aslot 'v with a curved jaws in the positions to which they may be brought in. the operation of the device, either opened or closed without liability of their' closed while they should remaih open, or vice versar 1 On the side of the arm G- opposite toy that at which the cutter-and binder aws are located is av ShOGtTZ of; iron or other suitable material pcnetratedlby the studs or bolts 9 and G and. retained by' the nuts'as This shoeis made with a thickened extremity T a-having arecess-.
